Triplet excitations at high temperatures in 1:1 TCNQ-salts

  • Published:
Czechoslovak Journal of Physics B Aims and scope

Abstract

High temperature properties of triplet excitations in TCNQ-salts are theoretically studied. Formulas for the energy and concentration of triplet excitons as functions of temperature are obtained. The static magnetic susceptibility of triplet excitons is calculated. A possible appearance of short range order in the excitation density is discussed. A high-concentration modification of the molecular exciton theory is used throughout the paper.
